function [y] = trig(x)
% trig(x)
% 	Parameters:
% 		x:	a time series
% 
% 	Outputs:
% 		y	a time series
% 	Purpose of this code: This code will return a time series corresponding to applying the function: 
% 	y = sin(2.*pi.*0.001.*x) to the given time series.
y = sin(2.*pi.*0.001.*x);
end
